Boot Device Not Found

[Jays23_]

I followed all troubleshooting steps and I still ran into the same "Boot Device Not Found" error in a blue box with a black screen. 
Is this fixable in any way? What should I do other than the f10 BIOS method (it didn't work).

Hi @Jays23_, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Since you've already tried the F10 BIOS method and still see the Boot Device Not Found error, here are some additional troubleshooting steps you can take:

Check if the Hard Drive is Detected in BIOS

Turn off your laptop and turn it back on.

Immediately press F2 or F10 (depending on your HP model) to enter the BIOS.

Navigate to Storage or Boot Options.

See if your hard drive (HDD/SSD) is listed.

If it's not detected:

• The drive may be loose or faulty. Try reseating it (see Step 2).
• The boot sector may be corrupted. Try repairing Windows (see Step 3).

Reseat or Replace the Hard Drive (if not detected in BIOS)

Power off the laptop and disconnect the charger.

Open the back panel and carefully disconnect the hard drive/SSD.

Reconnect it firmly and try booting again.

If still not detected:

• The drive might be dead. Try replacing it or connecting it to another PC via an external adapter to check if it's readable.

Repair Boot Configuration (if drive is detected)

If the hard drive appears in BIOS but won't boot, you might need to repair Windows:

Method 1: Automatic Repair

1. Create a Windows 10/11 bootable USB drive (if you don’t have one, use another PC to create it via Download Windows 10).
2. Boot from the USB (press F9 or ESC to access the Boot Menu).
3. Select Repair your computer → Troubleshoot → Advanced options → Startup Repair.

Method 2: Manually Rebuild Boot Files

If automatic repair fails:

1. Open Command Prompt from Advanced Options.
2. Run these commands one by one:
   bootrec /fixmbr
   bootrec /fixboot
   bootrec /scanos
   bootrec /rebuildbcd
    
3. Restart and check if Windows boots.

Test the Hard Drive for Physical Damage

If the drive is still detected but you suspect corruption or failure:

• Boot into the HP Diagnostics Tool (F2 at startup) and run a Hard Drive Test.
• If it fails, the drive is likely faulty and needs replacement.

Reset BIOS to Default

• Enter BIOS (F10 at startup).
• Find the Load Setup Defaults or Reset BIOS to Default option.
• Save and exit, then restart.

Last Resort: Replace the Drive and Reinstall Windows

If all else fails, you may need to:

• Replace the hard drive with a new SSD for better performance.
• Reinstall Windows using a bootable USB.

I hope this helps. 

Take care and have a good day.
